CONTAlNlNG-'CAN- SPECIFICATION forming part of Letters Patent No. 792,242, dated June 13, 1905.

Application filed May 12, 1902. Serial Na. 106,909.

T0 ((,ZZ whom, it may conccrn:

Be it known that I, PHILIP S. TELLER, a citizen of the United States, residing at Alameda, county of Alameda, State of California, have invented an Improvement in Containing-Cans; and I hereby declare the following` to be a full, clear, and exact description of the same.

My invention relates to improvements in containing-cans; and it is especially applicable to cans which are designed to contain butter and like substances and a saline or other solution in which the contained substances must be continually submerged.

My invention consists in such a construction of the ca'n top or cover that a space or chamber is formed above the main body and contents of the can which can be filled with the liquid, so that the contents of the can will always be submerged, and in conjunction with this is a filling-opening and a supplemental cap which is soldered or otherwise hermetically sealed over the opening after the filling is complete.

Rcferring to the accompanying drawings, Figure l is a Vertical section through a can embodying my invention. Fig. 2 is a plan of the top.

In the paclting of butter it is desirable to place it in hermetically-sealcd cans which contain any desired or suitable quantity and to prescrve the butter' from deterioration by submerging it in a sufficiently-strong brine. These cans are conveniently made rectangular, but may be of any other suitable shape; but, the butter being lighter than the liquid,when it is attcmpted to fill the can before the cover is sealed the butter will rise or fioat up in the liquid and prevent the liquid from flowing over and submerging the butter, and the part which is thus left exposed soon becomes unlit for use.

lt is the object of my invention to provide a means by which the butter will be constantly submerged in the liquid. This is effected by forming an extension or chamber in the top of the can having` such dimensions that the butter cannot move up into it; but it can be filled with the saline solution and afterward sealed. The solution will thus remain upon the top and surrounding the butter within the body of the can and prevent it from ever being exposed above the surface of the solution. In addition to this the shape of the top is such as to prevent the cans being con veniently reversed when stored or shipped.

As illustrated in the present invention, A is a portion of the body of a can designed to contain butter. B is a cap or cover. These two parts are in the present case shown as being' made rectangular, and the cover can be4 soldered or otherwise permanently fiXed to the top of the can.

In my invention I form a cover with the raised chamber 2, which in the present case is shown as convex; but it may be of any suitable or desired shape. Such a chamber may be stamped in the material of which the main cover is made, so that they can be very rapidly formed.- In the center and top of the extension or chamber a small hole is made, as at 3, and a cap 4: is adapted to fit over this hole and to seal it after the can has been filled. The shape of the extension-chamber is such that if the can is filled with butter, which would be essentially rectangular in shape, it is afterward filled with the salt solution (the brine) and the extension or chamber is also filled with brine. The shape of the chamber is such that the butter cannot pass up into it, being' stopped by the angles 5 of the cover; but the liquid with which the hole is filled will constantly submerge the butter and prevent its being exposed to the air. The small hole 3 allows the can to be filled full of the salt solution, including the extended chamber, and after this is done the small cap 4 is soldered over the hole, thus completing the work. It will be understood that this chamber may be made of any suitable or desired shape without departing from my invention.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. An improved butter-can having a metal body rectangular in cross-section and of substantially uniform diameter throughout its length, said body having the top edge formed with a divergent upwardly-extending smoothsurfaced fiange; and a cover having a domeshaped centrally-located chamber, to maintain IOO a pi'eservative solution above the butter, and having` an uptnr'ned divergent Smooth-surfaeed flange litting' within the flange of the body said covel` having` at the base ot' the flange and conneeting` Said flange With the base of the dorne-shaped portion, and an annulai' portion 5 ada pted to prevent the buttei' rising into the dome-shaped Chamber.

2. An original package consisting of a can having' a sheetmetal body of substantially even diameter, and having` the top formed With a divergent upWardly-extending flange, a top having` a dome-shaped eentrally-loeated chamber, a snri'ounding upWardly-divei'gent fiange and an intermediate annular poi'tion to form PHILIP s.
